Abstract: A snow thrower comprises an impeller 12 which has forward facing blades which extend a short distance inward from the periphery of the impeller. The impeller blades are substantially rigid during operation, and the impeller cooperates with two side walls and a continuous rear wall which form the active impeller housing 14. The continuous rear wall has a first portion whose cross section is a circular arc and generally follows the periphery of the impeller mounted within it, and a second portion which extends forward and upward to define a substantially planar snow guiding surface which, in normal operation, guides the snow forwardly and upwardly as it leaves the area of interaction with the impeller. <IMAGE>

Abstract: Solvents evaporated in the dryer sections B1, B2, B3 of a multi-station printing press or the like are removed from the dryer exhaust by heating the dryer exhaust C in an oxidation chamber E. The oxidation chamber exhaust is utilised, as a source of heat for the air supplies of the dryers, a regulated portion of the heated oxidation chamber exhaust being recirculated to the dryer sections to form a portion of the air supplies thereof. The recirculated oxidation chamber exhaust is confined within a completely enclosed system to prevent exposure of the pressroom personnel thereto. In addition, a heat exchanger may be utilised to transfer a portion of the remaining heat from the non-recirculated portion of the oxidation chamber exhaust to fresh air in order to heat the pressroom. <IMAGE>

Abstract: A deviation detecting apparatus for a bandsaw blade in a bandsaw machine has an arm pivotally mounted at a location adjacent to the linear path of travel of the blade through the cutting zone. The arm is yieldably urged into slidable contact with one side of the blade, and is thus pivotally movable in response to lateral deviations of the blade. A control device is responsive to pivotal movement of the arm. The control device generates a control signal indicative of blade deviations.

Abstract: Reception of valid two-out-of-N incoming multifrequency signals is realized by employing a multifrequency detector (FIG. 1, 102) including a plurality of filters (FIG. 2, 202-1through 202-N) and a corresponding plurality of comparators (206-1 through 206-N). The comparators are jointly responsive to output signals from the filters and to a threshold level (RMS REF) dynamically generated (via 204) in response to the incoming signal for generating output pulse signals (103-1 through 103-N) representative of multifrequency tones which exceed the threshold level (RMS REF). The pulse signal outputs (103-1 through 103-N) from the multifrequency detector (102) are evaluated (by 105) to determine whether two and only two tones are present which meet a prescribed criteria. The criteria is that each tone be present for at least a predetermined minimum portion of a prescribed sampling interval and that both tones be present for at least a predetermined number of consecutive sampling intervals. Out-of-band signals are rejected while increasing receiver sensitivity to inband signals by maintaining the peak amplitude of outputs from the filters generated in response to a single tone incoming signal having a frequency midway between the center frequencies of adjacent ones of the filters (202-1 through 202-N) in prescribed relationship to the magnitude of the threshold level (RMS REF) generated in response to the single tone incoming signal (see FIG. 4). In one example, the peak amplitude of the filter outputs is substantially equal to the magnitude of the threshold level (RMS REF, FIG. 4).

Abstract: A multiple circuit brake system is proposed, in which a pneumatic and an electric brake circuit supply the front axle brakes and the rear axle brakes in an overlapping control. Between the two brake circuits a measuring point (5, 6) is provided for determining the braking power entering each brake circuit, and a compensating device (12, 13, 16, 17) is used, by means of which the more advanced braking power in one brake circuit can be reduced by the same amount as the lagging braking power in the other brake circuit increases. The sum of the braking powers then generates the required braking effect. In this way both brake circuits, that is the electric brake circuit and the lagging pneumatic brake circuit are always operative and an operating check occurs on each braking. The brake system can be used for preference on commercial vehicles. <IMAGE>
